Thanks for the link! It's cool to see real discussion happening. I'm actually coming more from Robert Lustig's attack on fructose, which I know is much more specific than carb intake in general. I was aware there was controversy about it-- obviously I shouldn't be so quick to name Taubes.

Really, as someone who very easily went from overweight to fit purely by replacing carbs with fats, I'm just very reluctant to accept the thermodynamic hypothesis.
